Scientists at Scripps Research used MINFLUX super‑resolution microscopy to reveal why the ion channel PIEZO2 is uniquely tuned for light touch. They discovered that PIEZO2 is intrinsically stiffer than its sibling PIEZO1 and is physically tethered to the actin cytoskeleton via filamin‑B, a connection that transmits localized indentation forces. Disrupting this tether converts PIEZO2’s response, making it sensitive to membrane stretch instead of poking. The work clarifies the molecular basis of tactile perception and links channel mechanics to sensory disorders caused by PIEZO2 mutations.
